in 16:30 u said that by y=mx is fixing as straight line...but in the polar coordinate system also x and y are fixed paths for different values of r n theta as circles only...so how in former case or in y = mx path,limit evaluated is wrong?
I have infinitely many doubts in every question, like in example 5 .. we just took a case that x and y are related to each other as x^2 + y^2 = 1 but if we take a different value like x = r*sin(theta) and y = r*sin(PHY) .. then how will we get the value 0 .. here it is not mentioned that x and y are related...
Sir your lectures are awesome. You explained all methods in single video.
Other normal RUclipsrs getting subs than from a IIT which is better than all private RUclipsrs
Thnk u so much sir 🙏🙏 no ads this channel.

it was really helpful sir

still it will be zero..as the factor r in numerator will be there...which when r tends to 0 will be 0.
Dear Sir, thank you very much .
Watch videos on polar coordinates or polar transformation of cartesian coordinate system. Your doubts will be cleared!
Ex-1 and Ex-5 are same but answers are not same how ?
in ex-1 denominator has x^4 whereas in ex-5 denominator has x^2
